NETTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 244,159, dated July 12, 1881,

Application filed February 14, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALBERT T. ANDERSON, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new anduseful Improvements in Netting-Machines, of which the following is a specification.

My invention relates to that class of nettingmachines in which a series of knots extending entirely across the web are made, the web then being fed forward the required distance for forming the next series.

Figure 1 is a side elevation of my machine, parts being represented as broken out. Fig. 2 is a plan of the same. I Fig.3 is a longitudinal vertical section taken on line as w of Fig. 2. Fig. 4. is a cross-section of parts and elevation of parts, taken on line 3 y of Fig. 3. Figs. 5, 6, 7, and 8 are sketches to illustrate the knot-forming action of the machine. Fig. 9 is a perspective view, showing the moving cross-bar to which the warp-cord carriers are attached, also showing the guiding-pins at the end. Fig. 10 shows in perspective the channels in which the guiding-pins of the crossbar move, also the springs which force, the guide-pins to move in the desired direction.

A represents the frame of the machine.

B, Figs. 1, 2, and 3, represents the warproll around which all of the warp cords are placed. This roll may be furnished with weights, springs, or some other frictional device for giving the proper tension.

B 13 B 3 Fig. 2, show a weighted takeup device. This device is also shown in section in Fig. 3, and is provided with adjustable weights B Figs. 2 and 3.

(3, Figs. 2, 3, and 9, is a cross-bar which serves to sustain and give motion to the warpcord carriers 0 (the number of these carriers to agree, of course, with the number of warpcords.) This bar 0 moves forward in a horizontal plane nearly to the end of its stroke. Then it moves forward and laterally; thence backward to nearly the end of its rearward stroke; thence backward and laterally to the completion ofits stroke, the motion being of that kind known among mechanics as a fourway motion. The bar 0, in its movements,

, as above described, is guided by means of pins 0 C, Fig. 9, which project downwardly from it, one at each end. One of these pins traverses in the channel 0 0 0 Figs. 2 and 10, while the other one traverses in the channel 0 0 Figs. 2 and 10. In the forward movement of the bar 0 the guiding-pin (J is in the channel c and continues there until it comes'in contact with the bent spring 0 Figs. 2 and 10, which throws the guiding-pin out of the channel 0 into the channel 0 at the same time causing the bar 0 to take a lateral motion endwise to itself, so as to cause the guidingpin 0 in the opposite end of the bar 0 to pass through the channel c to the channel 0. This pin now becomes the guide and continues to be the guide through the backward stroke; but when it comes in contact with the spring 0 it is thrown out through the channel 0, and the first-mentioned pin slides through the channel 0 to the channel 0 which again becomes the guiding-channel. Motion is communicated to the bar 0 by means of the link 0, Figs. 1, 2, and 3, the lever 0 pivoted'at O and the cam 0 A groove in the cam operates upon a projecting pin on the lever 0 0 O Figs. 2, 3, and 9, are a series of cordcarriers attached to the bar 0, Each of these cord-carriers is bent at right angles, and is provided withan orifice or eye through which the cord passes. (See Fig. 3.)

D D represent a series of cord and loop holders, shaped as shown in Figs. 2, 3, 4, 7, and 8, which are all attached at their lower ends to a, rocker-shaft, D. These cord and loop holders D are held in avertical position by means of the bent lever D and spring D the end of the bent lever D resting upon a wheel, D said wheel having two notches, 01 01 out into it, so

that at proper intervals the end of the lever D may be pushed by the action of the spring D into them, thus allowing the upper end of 0 the looper and holders D to swing forward, as indicated by the arrow, (see Fig. 3,) and drop the loop. The notched wheel D is attached to a shaft, B, (see Figs.1, 2, and 3,) said shaft being driven by the gear-wheel D 5 E E, Figs. 3, 6, 7, and 8, represent a series of vertical pins, which serve as loop-holders, and are attached to a cross-bar, E Fig. 3, and receive from this cross-bar a vertical motion at proper intervals. This vertical motion is I00 communicated to them bya cam-groove in the cam E Fig. 1, there being two of these cams,

one at each end of the bar E These cams E are attached to the shaft E, which is driven by the gear E, Fig. 1.

E E are a series of pins, (see Figs. 3, 6, 7, and 8,) which are placed severally over the corresponding loop-holding pins E, and which are attached to a cross-bar, E, which is caused to move up and down at intervals by means of links, one of which is shown at E, Fig. 1. The links E are operated bya pin, E, Fig. 1, which works in a second groove made in the cam E The ends of the bars E and E are reduced in size, so as to pass through slots in the frame of the machine, one of these slots being shown at M, Fig. 3. The ends of these sets of pins E E are beveled, as shown, so that when they come together an'overlapping joint is formed, it being necessary to have an overlap of somekind, so as to retain the cord while the knotis being tied.

The narrow slot 6 made in the cross-piece E Figs. 3 and 4, serves to prevent thecompleted fabric from moving up or down, and thus to keep all of the cords in such a horizontal position as will admit of the proper action of the knot-forming parts of the device.

The rolls F F, Fig. 3, are geared together by spur-gears F F, (see Fig. 1,) and are operated by a link and pawl device, F Fig. 1. These: rolls move intermittently and serve to With-i draw the completed net as often as aseries of knots are made by the machine. serves as a receiver for the completed net.

H H represent a series of shuttles placed in shuttle-carriers H, each of these shuttle-carriers being attached, by any convenientmethod,

to the shuttle-bar H Figs. 1, 3, and 4. This shuttle-bar H slides in a frame, h H (See Figs. 1 and 4.) This frame h H H which we will call the shuttle-frame, slides vertically in ways attached to the side of the machine, onev of these ways being shown in Fig. 1. Two sprrn gs, H H", (see Fig. 4,) are attached to the lower ends of the parts H H, and serve to.

throw the shuttle-frame upward, it being drawn down by cams, one ofwhich, H H", is shown in Fig. 1. These cams are attached to the shaft D, one at each end, and in revolving come in contact with the shoulder h, Fig. 4, made on the lower end of the piece H.

H H" H H" are two levers attached to the shuttle-frame, and pivoted at h, as shown in Figs. 1 and 4. The upper ends of these le-v vers H H are connected to the shuttle-bar H (see Fig. 4,) their lower ends being operated upon by wedge-shaped projections El H (shown in Figs. 1 and 4) on the alternate ends of the cams H 11. As these cams revolve they alternately, at each half-revolution, act

upon the levers H H, and thus move the shuttle-bar H laterally. This lateral movement of the shuttle-bar always takes place when the shuttle-frame is at its highest point.

I prepare my machine for operation as follows: The warp-cords are drawn from the roller B over the part B and under the part The roll Li B of the take-up, (see Fig. 3,) thence through the carriers past the loopers, through the opening 6, over the roll F, and between it and the roller F thence partly around and under the roller F, and thence to the receiving-roll L, to which they are fastened. The shuttlespools H are filled with cords and placed in the carriers H. We will suppose the parts of the machine to' be in the position shown in Figs. 1, 2, 3, 4, 5, and 6. Now the machine starts, the first movement being that of the warp-carriers G the eyes W of these carriers traversing and 'carryin g the cords through paths indicated by w w 10 20 to 10. (See Fig. 5.) This operation when completed leaves the warpcord with a loop formed atdon the loop-holder D, and with a loop on the pin E, and also with the part W as shown in Fig. 7. All other parts of the knotting devices having remained stationary up to this time-that is, until the warp-cord has assumed the position represented in Fig. 7-the shuttles now move downward, being so placed, adjusted, and inclined (see Fig. 4) that the cord W, Fig. 7, slips .between the shuttle and the side h as the shuttle descends; but as the shuttle ascends the warpcord W passes between .the shuttle and the side h From the fact that the shuttle is inclined, as shown in Fig. 4, (the path of the upper part of the shuttle is on one side of the warp-cord W .and thepath of the lower part of the shuttle is on the other side,) the shuttle in descending will pass upon one side of the cord, and in ascendingwill pass upon the other side, thus placing the shuttle=cord S around the warp-cord W Whilethis operation has been taking place the pins E and E have closed and the looper D hasswung downward, so as to release the loop formed by the cord W W. The take-up device will draw the cords about the pins E E and form the knot, as shown in Fig. 8. At the next movement the pinsE and E open and the knot slips oft then the feeding action of the pawl device F takes place and draws the fabric the desired distance for one mesh.

By a careful examination of Fig. 7 it will be seen that from the peculiar shape of the looper and holder D, referring especially to the deep lateral notch 01, the warp-cord W is located in a vertical plane which passes through the middle space between the threads W W, so that the shuttle may pass and repass through the loop formed by the cords WV W without affecting either, its action being entirely upon the cord W One series of knots having been tied by the process above described, a second series is formed, the action being in all respects the same, except that while the shuttlebar is up it is thrown over by one of the levers H B, so that each shuttle will act upon a (lif ferent warp-cord, so as to produce a diagonal mesh. At the third movement the shuttles act upon the same warp-cords that they acted upon in the first movement, each shuttle acting alternately upon one of two warp-cords. The knot produced is of the kind called the weavers knot.

I claim as my invention- 1. In a netting-machine, the combination of 5 the single warp-roller B andthe take-up BJB B B with the bar 0, warp-carriers O link G,-lever O and cam 0, all operating together substantially as described, and for the purposes set forth.
